    Abstract: A method for concurrent execution of multiple protocols using a single radio of a wireless communication device is provided that includes receiving, in a radio command scheduler, a first radio command from a first protocol stack of a plurality of protocol states executing on the wireless communication device, determining a scheduling policy for the first radio command based on a current state of each protocol stack of the plurality of protocol stacks, and scheduling the first radio command in a radio command queue for the radio based on the scheduling policy, wherein the radio command scheduler uses the radio command queue to schedule radio commands received from the plurality of protocol stacks.

    Abstract: Embodiments of the invention provide a method for performing network resource allocation over hybrid networks so that application QoS requirements are met. The hybrid networks are represented as an undirected weighted graph with the communication links as edges irrespective of the communication medium. A QoS-based resource allocation model. Another embodiment further includes utility functions that capture the QoS attributes such as reliability, timeliness, fault-tolerance and lifetime allows determining routes and bandwidth allocation such that the total system utility across the entire network is maximized.

    Abstract: Excessive latencies and power consumption are avoided when a large number of leaf nodes (LNs) contend simultaneously to join a time slotted channel hopping wireless communication network having a root node (RN) interfaced to LNs by one or more intermediate nodes (INs). A first plurality of shared transmit/receive slots (STRSs) is allocated for at least one IN, and a second plurality of STRSs is advertised for use by contending LNs, where the first plurality is larger than the second plurality. When a LN joins, its STRSs are re-defined such that most become shared transmit-only slots (STOSs) and no STRSs remain. The numbers of STRSs allocated to INs may vary inversely with their hop counts from the RN. One or more STOSs may be added for each of one or more INs in response to a predetermined network condition.

    Abstract translation: 当大量叶节点（LN）同时竞争加入具有通过一个或多个中间节点（IN）与LN接口的根节点（RN）的时隙信道跳频无线通信网络时，避免了过多的延迟和功率消耗。 为至少一个IN分配第一多个共享发送/接收时隙（STRS），并且通过竞争LN来通告第二多个STRS以供其使用，其中第一多个大于第二多个。 当LN连接时，其STRS被重新定义，使得大多数成为共享的仅发送时隙（STOS），并且不保留STRS。 分配给IN的STRS的数量可能与RN的跳数相反。 响应于预定的网络条件，可以为一个或多个IN中的每一个添加一个或多个STOS。
